The TikTok algorithm is the secret that all creators want to know. It is so powerful and relevant that even users have noted its effectiveness. Knowing how it works means ensuring views, engagement and also sending your TikToks to the TikTok For You feed.
But what exactly is the TikTok algorithm?

The success of TikTok is largely due to very advanced algorithms that provide videos based on users' interests. It is a very detailed analysis of everyone's tastes and adapts to offer the most suitable content to the user, at the best time. The Utopia agency will today explain how the Tiktok algorithm works: its secrets and how to take advantage of it.

TikTok's Infinite Scroll

You may have already heard of this term: infinite scroll. It is this news feed that you can scroll infinitely and that will always offer you content. For Instagram, 80% of it is composed of content that comes from your subscriptions.

For TikTok, it is composed of 100% content that is still unknown (the Pour Toi page, also called For You Page #fyp).

This is what makes TikTok strong: novelty, but relevant and well-targeted novelty. In order to be able to be at the forefront of relevance, TikTok has set up a powerful algorithm that will offer personalized content according to the preferences, tastes and habits of users.

What everyone therefore wants to know is what are the criteria to be able to appear on this For You page and be visible by the algorithm.

You are lucky, TikTok has unveiled some interesting ideas.

In short, it's all about machine learning.

Each user action is analyzed by the algorithm that will define a typical persona and offer appropriate content. Depending on whether the user likes a video, comments on it, watches it, watches it, shares it...

This is also the strength of TikTok: content first.

The For You page is not just for superstars, quite the opposite! There are many stories of creators with 50, 100 or 500 subscribers who enjoy a video with 1 or 2 million views in less than 24 hours!

Once published, your TikTok will go through a funnel of 3 steps:

Step 1: Review TikTok rules and guidelines

NLP and TikTok metadata will analyze all the content of your video. It will analyze:

  1. The visual elements
  2. The audio
  3. The language
  4. The volume
  5. The legends
  6. The subtitles
  7. The hashtags
  8. The titles
  9. The name of the video file

This drastic check will first analyze whether or not the content has a place on TikTok. Therefore, let him respect TikTok community rules

In a second step, he will provide the necessary resources to make the first broadcast on TikTok:

Step 2: First release to a sample

TikTok content is going to be broadcast to a small sample of your community and a few strangers. The objective is to set up an evaluation based on the actions of users of your content. This will allow TikTok to know whether or not your content was liked and that it has room to be broadcast more to a wider audience.

Step 3: The performance evaluation score

It is according to this score, that TikTok will propel your content to millions of views or take it to oblivion. This rating ratio will be a score out of 30 points. The closer we get to 30, the more likely we are to have content that will go viral on the For You page.

Review rate = 10 points (it's the action of re-watching a TikTok)

Completion rate = 8 points (This is the percentage of the video watched. A half-watched video will have a ratio of 0.5, so 4 points)

Shares = 6 points (the action of sharing a video to other users)

Comments = 4 points (Based on the number of comments below the video, as well as their relevance)

I like = 2 points (The lowest scale, but essential)

As you can see, TikTok goes all out on viewing time. And this is where you should put it too!

TikTok is the opposite of Instagram. Here, we focus on the story, the hook and the process. On Instagram, we focus on the result and the end.

It's up to you to play now!
